This is a non-provisional claiming priority to provisional application No. 60/880,001, entitled Re-Fresh Sports Bottle, filed on Jan. 11, 2007, and provisional application No. 60/898,630, entitled Re-Fresh II, filed on Feb. 1, 2007 which are hereby incorporated by reference in their entirety.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to beverage bottles typically referred to as sports bottles.
2. Description of the Prior Art
With the advent of a health conscious society, sports bottles have become particularly popular for carrying hydration beverages, electrolyte rich fluid for flavored or high energy drinks. These bottles are often constructed of plastic material and are typically single fill bottles such that once the contents have been consumed, the bottles themselves are frequently disposed of and find their way to landfills or the like thus contributing significantly to the bulk of discard in the landfills.
Efforts have been made in various areas to provide for a convenient dispensing bottle with a container of liquid, such as water, attached thereto. Such devices typically incorporate some type of communication valve or the like which is manually operable to open communication from the water reservoir to the baby formula bottle for introduction of water to be consumed by the newly fed baby. Such devices have been proposed with a male connector plug externally threaded on opposite ends for threadable connection between the baby bottle and a reservoir and incorporating the manually operable valve. A device of this type is shown in U.S. Patent Application No. 2007/0017890 filed Jun. 25, 2005. Such devices, while having utility for direct communication between a water reservoir and interior of a baby bottle, suffer the shortcoming they are relatively expensive to manufacture, are cumbersome and, with reuse, sometimes encounter sanitation challenges.
Participants and spectators alike at various sporting events and gathering places often times carry beverage bottles with them. Frequently, the beverage bottles are carried in backpacks or sometimes mounted to the frame of a bicycle or the like. Athletes are often clad in tight fitting uniforms without pocket space for carrying necessary items such as car keys, credit cards, cell phones or the like for easy access. Thin wall molded water bottles have been proposed with an external screw thread on the bottom to connect with an interior screw thread of a storage cup for storage of car keys and the like. A water bottle of this type is available from Hangzhou Everich Houseware Co., Ltd. While providing for convenient storage of car keys and the like, the screw thread connection of the cup is typically not designed to provide a water tight seal for carrying liquid or fine powder concentrate in the cup for repeated unthreading thereof for access to refill concentrate from a cup.
SUMMARY OF THE INVENTIONA combination bottle and concentrate container including a beverage bottle configured on its bottom end with a peripheral connector groove, a concentrate cup, opened at one end and formed adjacent to one end with a connector lip for releasably engaging the connector groove and a connector ring interposed between the bottle and cup and formed on one extremity with a lip for releasably engaging the connector groove and on its opposite end with a female coupling element for releasably engaging the cup.
Other features and advantages of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the features of the invention.
Referring to
Sports bottles have become popular with all segments of the public interested in a healthy life style and particularly those dedicated to fitness and training. Such sports bottles are often utilized to carry a beverage which may be an energy drink or other type of fluids for adding electrolytes or other liquids for hydration. Such sports bottles are typically single use thus resulting in discard when they become empty thereby contributing significantly to the bulk added to landfills each year. Thus, it is desirable to provide an economical and convenient combination bottle and concentrate container so that once the beverage is consumed from the bottle, the cap may be decoupled so that concentrate may be poured from the container cup into the bottle to be mixed with water or the like to thereby provide a refill thus continuing utilization of the same bottle.
The bottle 21 of the present invention may be constructed of any one of a various types of plastics and preferably of high density polyethylene. It will be sized for the particular application and will preferably have a volume of about 18 ounces to provide a convenient volume for mixing and to establish a reasonable supply of drinking beverage.
In one preferred embodiment, the combination of the present invention is of molded construction and the wall of the bottle and container cup may be relatively thin, on the order of 1/32″ thick and certainly less than 1/16″ of an inch thick and may be contoured to a generally cylindrical configuration. The bottle 21 is molded at its upper extremity with an annular, upwardly facing shoulder 41 surrounding an upstanding threaded neck for receipt of a cap 43 having a conventional valved drinking nozzle 45 mounted centrally thereon.
The bottle 21 is configured intermediately along its length with a radially inwardly indented groove defining a waist 47. The bottle is configured at its bottom extremity with an undercut to define a reduced in diameter cylindrical boss 51 (
The coupling ring 25 is configured with a cylindrical peripheral wall 55 of a diameter to be slip fit in female relationship over the boss 51 and is formed at its upper extremity with a radially inturned segments defining the locking lip 33 received in snap fit relationship in the groove 31.
Referring to
The peripheral wall 55 of the ring is formed in its lower extremity with a plurality of radially inturned teeth 35 to facilitate coupling to the cup 23.

Referring to
With continued reference to
Referring to
A tubular cap 85 is received in friction fit sealing relation over the top end of the spout 103 and a friction fit plug 86 is formed with a male nipple 88 received in friction fit in the top end of the tube 103.
In operation, the bottle 21, cup 23, ring 25 and lid may be molded from flexible plastic such as polyethylene. The combination may then be assembled together by grasping the coupling ring 25 and pressing it upwardly on the boss 51 shown in
A charge of concentrate, baby formula, water or the like may be inserted in the cup 23 and the lid 91 placed there over by inserting the barrel 93 downwardly into the top of the cup and pressing downwardly to flex the latching bead 97 and wall of the barrel radially inwardly so such bead can pass axially downwardly past the annular edge 77 of the flange to clear such flange allowing the flange to nest in sealing relation in the annular groove formed between the bead and the underside of the flange 95 (
The bottle 21 may then be used in a conventional manner. When the athlete desires hydration or re-energization he or she may access the valved nozzle 45 for a reconstituted beverage. When the bottle 21 is emptied, it would be appreciated that the athlete may quickly and easily disconnect the cup 23 by rotating it clockwise as shown in
This process may then be repeated until such time as the concentrate has been depleted from the cup 23. Then with the cup decoupled from the ring 25 and the athlete may grasp the tab 102 (
Referring to
Referring to
As will be appreciated by those skilled in the art, the bottle cap 43 may take many different forms, such as a squirt or pour spout or, in some embodiments, a spray nozzle.
From the foregoing, it will be apparent that the combination beverage bottle and concentrate of the present invention provides an economical and effective means for making and assembling a concentrate cup for convenient coupling to a beverage bottle and which is convenient to use and provides for a sanitary and orderly containment of concentrate ready for addition to the beverage bottle.
